Damien1972 writes: More than 60 percent of Africa's forest elephants have been killed in the past decade due to the ivory trade, reports a new study published in the online journal PLOS ONE. The study warns that the diminutive elephant species — genetically distinct from the better-known savanna elephant — is rapidly heading toward extinction. The study is based on the largest-ever set of survey data across five forest elephant range countries: Cameroon, Central African Republic, the Democratic Republic of Congo, Gabon and the Republic of Congo. The study involved more than 60 scientists who spent 91,600 person-days surveying for elephants, walking over 13,000 kilometers.
